Valley Classic Control Panel
25
Overview
Volt Meter
The volt meter displays the voltage being delivered to
the machine from the control panel. See Figure 25-1.
The recommended operating voltage is the nominal
supply voltage. See Figure 25-2.
During normal operation the meter should read ap-
proximately the nominal supply voltage. See Figure
25-2.
NOTE
• Some long or high amperage machines may
need to be run at 500 VAC, 60 Hz (400 VAC, 50
Hz) minimum.
!
CAUTION
•
DO NOT OPERATE THE MACHINE IF THE
VOLT METER READS BELOW THE MINIMUM
ALLOWED VOLTAGE OR ABOVE THE MAXI-
MUM ALLOWED VOLTAGE. SEE FIGURE 25-2.
• OPERATING THE MACHINE OUTSIDE THESE
LIMITS COULD CAUSE DAMAGE TO THE
DRIVE MOTORS AND OTHER ELECTRICAL
COMPONENTS.
•
CORRECT THE LOW VOLTAGE PROBLEM
BEFORE RESUMING OPERATION.
